Ornithogalum plant named &#39;BCOR-09.002&#39;

ABSTRACT

A new and distinct cultivar of  Omithogalum dubium  named ‘BCOR- 09.002 ’ resulted from a controlled hybridization of commercial varieties. The cultivar ‘BCOR- 09.002 ’ has R.H.S. 11 B (yellow group) tepals, erect and strong racemes which resist bending under low light conditions, a long blooming habit and broad, channeled leaves.

Botanical classification: Ornithogalum dubium ‘BCOR-09.002’.

Variety denomination: ‘BCOR-09.002’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct cultivar of the Lilaceaefamily. The botanical name of the plant is Ornithogalum dubium‘BCOR-09.002’.

The new cultivar is the result of controlled crossing of commercialvarieties.

The new variety ‘BCOR-09.002’ is differentiated from other commercialvarieties known to the inventor as shown in the table below.

The new variety is suitable for commercial sale as a potted plant.

The new cultivar ‘BCOR-09.002’ has been asexually reproduced undercontrolled environmental conditions at a nursery in Half Moon Bay,Calif. under the direction of the inventor with its distinguishingcharacteristics remaining stable.

Asexual reproduction was first accomplished when vegetative cuttingswere taken from the initially selected plant. Examination of asexuallyreproduced, successive generations grown in a nursery at Half Moon Bay,Calif. shows that the combination of characteristics as herein disclosedfor ‘BCOR-09.002’ remains firmly fixed.

-   The plant:    -   -   Origin.—Controlled cross of commercial varieties.        -   Form.—Spreading basal leaves with upright inflorescences on            tall rachis. A typical plant with a mature inflorescence            that is ready for sale at ten months is approximately 25 to            40 cm high when grown in a 6″ pot with appropriate soil            amendments. Plants shown are 40 cm high.        -   Growth.—Upright rachis with somewhat reflexed leaves.            Inflorescence is large and showy.        -   Rachis.—The rachis is upright and glaucous. Its color varies            between R.H.S. 146 D (yellow-green group) when younger and            R.H.S. 146 A (yellow-green group), at maturity of the            inflorescence. Diameter is 9 mm. The length of the rachis to            the first floret and bract pair is 25 cm. Rachis or stem at            its base is 10 mm in diameter.        -   Foliage.—Usually three to five leaves surround each rachis            on a mature plant ready for commercial sale. Leaves are            whorled at base of stem. Shape of leaf. — Fleshy,            channel-shaped, lanceolate. Margins are entire. Apex is            acute. Texture. — Glaucescent. Color. — Mature leaves are            R.H.S. 144 A (yellow group) on both abaxial and adaxial            surfaces. Large leaves are 17 cm long and 4.5 cm wide.            Immature leaves are R.H.S. 137 C (green group).-   Inflorescence:    -   -   Form.—Corymbose racemes. Indeterminate. Approximately 50 or            more individual florets per inflorescence on pedicels that            elongate as the florets opens, and on average are as long as            120 mm for mature florets. Apical buds on developed            inflorescences are predominately green — R.H.S. 145 D            (yellow-green group), with their apex being R.H.S. 146 B            (yellow-green group), 0.9-1.0 cm tall and have diameter of 3            mm wide. The rachis for the inflorescence is strong and            upright. The pedicels are glabrous and similar in color to            the rachis at their point of attachment.        -   Size of inflorescence.—Large. A typical inflorescence at            this age, as shown in the figures can be 18 cm high.        -   Shape.—Basal florets opening first with pedicels that            elongate that give the raceme a corymbose appearance as the            inflorescence ages.        -   Appearance.—Showy.-   Florets:    -   -   General.—The florets at the base of the inflorescence open            first, and open more and more as the inflorescence ages.            Florets are perfect and complete. Perianth is not keeled.            Each floret is associated with a bract that can be as wide            as 20 mm and as wide as 15 mm and as high as 27 mm when            floret is beginning to open, and has tips that are R.H.S.            137 B (green group). Tips of bract are darkest part of            bract. Bracts retain color. The bracts are ovate with            narrowly acute apexes and relatively wide bases and            reflexed/curled edges around rachis. Perianth: There are 6            ovate tepals that are spotted at their bases on both their            abaxial and adaxial surfaces. The spot is R.H.S. 152 A            (yellow-green group) on the adaxial surface. The abaxial            spot is R.H.S. 143 A (green group). Spot fades as floret            ages. The tepals are predominantly R.H.S. 11 B (yellow            group). Floret diameter: 40 mm. Tepals of mature florets are            typically 30 mm high, 20 mm wide at their widest point, and            5 mm wide at their attachment. Immature tepals have spotted            base, the spot is approximately 7 mm high and extends the            width of the tepal at the base. Apex shape of the tepal is            abruptly acuminate.        -   Stamens.—6 stamens (two sets of 3). Pollen is R.H.S. 14 A            (yellow-orange group). Plant produces abundant pollen.            Filament is wide with basal wings. Filament is 3 mm wide at            base and 4 mm high. Anther is 3 mm high and basally            attached. Filament base is R.H.S. 155 A (white group).            Anther is R.H.S. 152 B (yellow-green group) before opening            to reveal pollen.        -   Stigma.—Generally, a three-pronged stigma on one pistil per            floret. The style is 2 mm long. The stigma is approximately            2 mm long.        -   Ovary.—The ovary is three-celled with axile placentae. The            top of the ovary is R.H.S. 139 A (green group). The ovary is            7 mm high and has a diameter of 4 mm.        -   Fragrance.—Florets product a very mild citrus fragrance.
